Pcm Code P098 - Park/Neutral-To-Drive/Reverse Shift While In ISC Control Range: Notes

This test monitors idle speed and gear selection from Park or Neutral to Drive or Reverse when throttle is in ISC speed range. If idle speed is greater than desired, PCM will retard spark advance and set code.

PCM Code P098 could be driver-induced by shifting into gear with throttle angle of less than 20 degrees with throttle depressed.
